Metric System The metric system (SI) is an international system of measurement that is based on units of 10.

Matter Anything that has mass and takes up space.
All the “stuff” around you is matter.

Volume Volume- The amount of space matter occupies Liter(L) cm3
Measurement Tools Units Volume- The amount of space matter occupies Graduated Cylinder Metric Ruler Liter(L) cm3

Mass Mass- The amount of matter in an object. Gram (g)
Measurement Tools Units Mass- The amount of matter in an object. Triple-beam or Digital balance Gram (g)

Length Length- How far away two points are from each other. Meter (m)
Measurement Tools Units Length- How far away two points are from each other. Metric Ruler Meter Stick Meter (m)

Prefixes & Converting Prefixes are placed in front of a base unit to change the size. To convert to a Smaller Unit: Move the decimal point according to the number of “jumps” or multiply by the conversion (10, 100, 1000…) To convert to a Larger Unit: Move the decimal point according to the number of “jumps” or divide by the conversion (10, 100, 1000…)

How many jumps does it take?
1 2 3 KILO 1000 Units HECTO 100 Units DEKA 10 Units DECI 0.1 Unit Meters Liters Grams CENTI 0.01 Unit MILLI Unit 4 km = _________ m Starting Point Ending Point 1st – Determine your starting point. 2nd – Count the “jumps” to your ending point. 3rd – Move the decimal the same number of jumps in the same direction. How many jumps does it take? 4. 1 __. 2 __. 3 __. = 4000 m

A pneumonic device we use to remember the prefixes is:
